Two students are arguing over the differences between speed and velocity. one student says,
“speed is a scalar because it describes how fast an object is traveling. velocity is a vector because it tells how fast and in what direction an object is traveling.” which of the following statements is correct? (aks 1b3 dok 3)
question 3 options:
the student’s understanding of all four terms (speed, velocity, scalar, and vector) is correct.
the student’s understanding of speed and velocity is correct but their understanding of scalar and vector is incorrect.

Use the library or internet to research each planet. make a chart comparing the following: approximate surface temperature relative surface gravity compared to earth atmospheric gases water in any form: solid, gas, or liquid when you have completed your chart, use the information you have collected to answer the following questions: which is the hottest planet? which is the coldest planet? which planet's temperature is closest to that of earth? (note: water boils at 100°c/212°f. water freezes at 0°c/32°f) which planet has the greatest gravitational attraction? which planet has the least gravitational attraction? which planet's gravitational pull is closest to that of earth? do any of the planets have oxygen in their atmosphere? which planet's atmosphere most resembles that of earth? do any of the planets have flowing water? which planet's water resources (solid, gas, or liquid) might be close to the amount on earth? which planet most resembles earth in terms of all of the factors: temperature, gravity, atmosphere, and water? if earth became an uninhabitable planet, which planet do you think would be the next best to live on? explain your answer.
